  摘要：

  The reaction of Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(2) with triflic acid, pentafluorophenol, HBF4 . OEt(2), or [H(OEt(2))(2)](+)[BAr4F](-) (Ar-F = 3,5-C6H3(CF3)(2)) yields complexes of the general formula Re(C-t-Bu)(CH2-t-Bu)(3)X (X = OTf, OC6F5, BF4, BAr4F) in 60-80% yield. Re(C-t-Bu)(CH2-t-Bu)(3)X reacts with coordinating ligands L (L = py, CH3CN, CD3OD, THF) to form neopentane and Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(L)(n)X (n = 1-3). The reaction of Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(py)(2)(OTf) with NaC5H5, NaL(OEt) (L(OEt) = [CpCo(PO(OEt)(2))(3)], or NaHBpz(3) in THF yields Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(eta(5)-C5H5), Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(L(OEt)), or Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(HBpz(3)), respectively, while the reaction between Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(py)(2)(OTf) and 1,4,7-trithiacyclononane produces colorless [Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(eta(3)-S3C6H12)](+)[OTf](-) in 96% yield. Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(L) (L = Cp, L(OEt)) and [Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(eta(3)-S3C6H12)](+)[OTf](-) react with triflic acid to form Re(C-t-Bu)(CH-t-Bu)(L)(OTf) or [Re(C-t-Bu)(CH-t-Bu)(OTf)-(eta(3)-S3C6H12)](+)[OTf](-), respectively. A similar reaction between Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(L(OEt)) and [H(OEt(2))(2)](+)[BAr4F](-) in ether produces [Re(C-t-Bu)(CH-t-Bu)(OEt(2))(L(OEt))](+)[BAr4F](-). Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(py)(2)(OTf) reacts with H2C=CHR (R = OCH2CH3, C6H5) to yield neohexene and Re(C-t-Bu)(CHR)(CH2-t-Bu)(py)(2)(OTf) complexes. Re(C-t-Bu)(CH-t-Bu)-(CH2-t-Bu)(py)(2)(OTf) reacts with ethylene to form the unstable methylidene complex, Re(C-t-Bu)(CH2)(CH2-t-Bu)(py)(2)(OTf), which can be trapped upon addition of bpy to yield red Re(C-t-Bu)(CH2)(CH2-t-Bu)(bpy)(OTf). Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(py)(2)(OTf) reacts with excess ethylene to form colorless Re(C-t-Bu)[(CH2)(3)-t-Bu](C(2)H4)(py)(2)(OTf) in 85% yield. Re(C-t-Bu)(CH-t-Bu)(CH2-t-Bu)(CH3CN)(OTf) metathesizes 100 equiv of cis-2-pentene in less than 5 min, but the catalyst is not long-lived.
